Specification of Letters Patent.

Iatented June 2, recs.

Application filed Iiovember 9, 1906. Serial No. 342,679.

To all whom it may concern:

Be it known that I, Isrnon of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, and useful Improvements in Telegraphy, of which the followi is a specification.

M invention re ates to an im rovement in te egraphy and has more specia reference to the receivin device of a telegraphic system wherein t e impulses are transmitted either through the natural medium or over a metallic circuit.

The advantage of the invention, as later on to be described in this specification, illustrated in the drawing and more particularly ointed out in the claims following the specicati'on, is more 'a parent in a telegraphic system wherein sit or rapidly recurring or a ternati'ng impulses, or electric Waves, such as are used in wireless, are transmitted.

The underlying principle ofthis, my invention, consists in producing explosions through the incoming impulses and operating a translating device through such explo sions.

To produce an explosion of a material, such for instance as gas, it is necessary to raise the tem erature in the region of this material, and in telegraphy, such for instance aswireless telegraphy, 1t is only necessary to either insert in the receiving circuit a very high resistance, such for instance as a short platinum wire of small dimension, or where the impulses are of sufficient strength, to simply produce a spark-gap between two parts of the receiving circuit.

Different materials may be used as the explosive medium, but I have illustrated in the accompanying drawing the explosive medium as to consist of a mixture of oxygen and hydrogen, for the reason that a mixture of these two gases can be'exploded at a very low temperature and for the further reason parting from that the presence of hydrogen reduces the resistance of the air-gap as to the incoming impulses.

For the purpose that persons versed in the art'may practice this, my invention, I have illustrated difierent arrangements embodying said invention, but it is obvious that these arrangements may diiferfwithout dethe scope of my invention. Referrin to the drawing, Figure 1 is a partially p an and partially sectional view,

KIrsEE, citizenhave invented certain newwith the-electric circuit in diagram. Fig. 2 is a modified form of Fig. '1 and Fig. 3 1s a sectional view of part of the exploding chamber with the annunciating device in p an. 1

In Fig. 1, l1 and 12 are the two parts of the receiving circuit. In a wireless system 11 may be connected to the aerial conductor and 12 to the ground. In a system with metallic conductors, they are adapted to be connected to theconductors proper.

8 and 9 are the terminals connected to the Wires 11 and 12 and between the terminals are the heatin means, here shown as an air-gap and designated by the numeral 10.

1 and 2 are reservoirs of gases; one of these reservoirs is sup osedto contain here oxygen and the second of these reservoirs is supposed to contain hydrogen, both under pressure.

3 and 4 are the valves for these two reservoirs so that with these valves the ratio of.

the ases issuin from-the reservoirs may be regu ated at wi I 5 and 6 are-the pi es connecting the reservoirs 1 and 2 with t e mixing pipe 7.

13 is the explosive chamber rovided with the check valves 14' and 15. t is suggested that the check valve 14, should answer to lower pressure than the check valve 15.

17 is a wire connecting here with one terminal to the check valve 15 and with the other terminal to one pole of a source of current, hereshown as the battery 19, the other,

pole of'which is connected with the electromagnetic device 20. This electro-magnetic device may embrace any" of the desired translating devices, such for instance as a sounder or other means to givethe necessary annunciation or recording. The free terminal-of the coil of this device'is connected through wire 18 to the adjustable contact 16 the free end .of which is near the check valve 15. The operation of this device-is as fol- Through this explosion, the check valve 14 willbe closed tig ter but the check valve 15 will be opened and through this movement voir 1 will be cut off an Wlll flow into the chamber 13. The operae be brought in connectionwith the adjustable contact 16, thereby closing the circuit containin the battery 19 and electro-magnet 20. The e ectro-ma net will therefore be energized; After t e explosion has-spent its force, the check valve 15 will, by its own weight, fall again in its normal position, thereby breaking the circuit and the electromagnet will be deenergized. As long as the force of the explosion holds the check valve 14 down, no further gases will issue from the pipe 7, but as soon as the explosion has spent its force, the check valve 14 will be removed of this counter-pressure and the pressure of the gases from 7 will suffice to' overcome the weight of the check valve 14 and will issue again in the chamber 13.

In Fig. 2, I have provided means to automatically cut ofi the flow of gases, after the explosive chamber is filled with thenecessary quantity of same and these automatic means are separate from the check valve 14 and consist of the valves 23 and connected together by the lever 26, pivoted at and provided with the spring 31 and thearmature 27. In this figure, I have substituted for the two reservoirs only one reservoir containing the necessary gas or mixture of same. In this figure, I have also substituted instead of a plain air-gap, a resistance wire adapted to be heated and numbered the same as 10.

In its normal position, the s ring 31 will keep the valve 25 open and t e valve 23 closed, but asit is necessary to provide the chamber 13 with the necessary gas, the valve 23 1s once opened by the o erator and at the same time the valve 25 clbsed. The small reservoir 24 will then be filled with gas under pressure and in closing the valve 23 and opening the valve 25, the supply from thereserthe supply from 24 tion of this arrangement is as follows:

When the device is brought in use, the chamber 13 has to be filled, as stated above, by the operator with the necessary explosive gas. mains at the low temperature, the gas will remain in its normal'position, but as soon as the resistance 10 is heated, an explosion of osion will the gas will take place. This exp open the valve 15 and bring the same inconnection with the contact 16 closing the cir-' cuit including the electro'magnets- 20' and 22. As the electro-magnet 20is supposed to actuate the desired translatin device, the same will annunciate or recor the passage of this impulse; but the electro-magnet 22, when energized, will draw the armature 27 towards its core, will therefore 0 en the valve 23 and close the valve 25. T e reservoir 24.- .will now be filled with the gas under pressure When, now, after the force of the explosion is spent, thevalve 15 will fall back .core of said electro-magnet will .ized circuit and As long as the resistance wire 10 re-' in its normal position, the circuit embracing the electro-magnet 22 will be 0 ened, the

e denergized and the spring 31 will come in play, closing the valve 23 and openin the valve .25, thereby filling again the cham er 23 with the necessary gas.

In Fig. 3', I have omitted entirely the localprovide the valve 15 with the necessary striking arrangement 28 and in the region of same an annunciating device, here shown as a bell 29.

Where the mixture of gases consists of hydrogen and oxygen in proportion of two to one, no means need to'be provided for cleaning the space of the exploding chamber, as the combination of the two gases is water. But where other gases or vapors, or even if desired explosive solids, such for instance as gun cotton is used, then it is best to clean the chamber from the residue and any of the well known means maybe applied for such purpose.

It is obvious, that localized means may be employed to raise the temperature of the gas to a degree higher than the normal tem erature, but less than is necessary to i ame said gas. I have notshown such means, as the same may differ according to requirements and the heating of gases per se is well understood. So also can the resistance be raised by localized means to a temperature short of the temperature needed to inflame gases.

. Having now described my invention, what I claim as new and desire to secure by Letters Patent is f 1. In telegraphy, means to receive impulses and translate the same, said means embracing means operatively related to the receiving circuit to raise the temperature of a restricted area, an explosive medium in the re ion of said area and a local circuit adapte to be operated through the explosions of said medium, said local circuit embracing translatin device.
